Q: on my face and its SPF 30 will it last all day? i dont wanna get burned during 45 minutes of p.e.
A: Suntan lotion only lasts about 2-3 hours, so if it isn't too much of a pain, i'd bring some along to reapply, if you get burnt easily. I never burn, and never apply suntan lotion, which is probablly not a good thing. But, i'd just bring one of those handy spray on sun tan lotion bottles with you in your bag, if you want to be on the safe side!
